[0029] The center of the rotating block 13 is provided with a screw rod socket 132, and the peripheral position is provided with a connecting column socket 134. A push rod groove 136 is provided on the side wall of the rotating block 13.
[0030] The fixed block upper cover 15 and the fixed block lower cover 17 are respectively mounted and fixed on the top surface and the bottom surface of the fixed block 11 , and encapsulate the rotating block 13 in the rotating block mounting groove 112 of the fixed block 11 .
[0031] The push rod 19 is installed in the push rod slot 136 of the rotating block 13 , and its front end is rotatably pivoted on the rotating block 13 .
[0032] The rear end of the push rod 19 is rotatably pivoted to the front end of the connecting rod 21 .
[0033] The rear end of the connecting rod 21 is connected to a push-pull power device 23. The push-pull power device 23 is a cylinder or a motor, which is installed and fixed on the fixed block 11.
[0034] The push rod 19 and the connecting rod 21 are both installed in the fixed block 11 .
[0035] The lower fixing plate 25 is installed and fixed on the top of the threading mounting seat 29 and is located below the fixing block lower cover 17. A connecting column fixing hole 252 is provided on the lower fixing plate 25.
[0036] The connecting post 27 is inserted into the connecting post insertion hole 134 of the rotating block 13 , and the bottom end of the connecting post 27 is inserted and fixed in the connecting post fixing hole 252 , thereby improving the installation firmness of the rotating block 13 .
[0037] The threading mounting seat 29 is fixed on the bottom surface of the rotating block 13 and is located below the lower fixed plate 25. A wire clamping device accommodating groove 292 is provided on the front surface of the threading mounting seat 29.
[0038] The left wire clamping device 31 and the right wire clamping device 33 are respectively installed at opposite positions on the left and right sides of the wire clamping device accommodating groove 292.
[0039] The left wire clamping device 31 includes an upper left wire clamping rod 311 and a lower left wire clamping rod 313 at upper and lower positions.
[0040] The right wire clamping device 33 includes a right upper wire clamping rod 331 and a right lower wire clamping rod 333 at upper and lower positions.
[0041] The left and right wire clamps 31 and 33 can both move in opposite directions. When clamping the wire 1000, the left and right wire clamps 31 and 33 move toward each other and merge together. When releasing the wire 1000, the left and right wire clamps 31 and 33 move in opposite directions and separate.
